CoppeliaSim forums

Hi all, I'm practicing with dynamic simulation in CoppeliaSim and trying to figure out how things work under the hood. I've read the related pages of the documentation, but I couldn't find there answers to some questions arisen from some tests I did. In detail, I created a very simple actuated pendu...

Hi, I would like to dynamically simulate the insertion of a shape into a multi-layer object. In particular, I'm trying to simulate a "rupture" event of the collision, e.g., due to a sufficiently high resulting contact force. As a result of such rupture, what I would like to achieve is the ...

Hi, I would like to use the distance calculation module provided by the simulator. By reading the corresponding sections of the documentation and the related APIs, I see that it is possible to access the minimum distance between two separated shapes. However, I would like to know if it is possible t...

Hi, I'm experiencing a crash in the new version (3.6.1) of V-REP, running in Linux Ubuntu 16.04, whenever I close the panel to command position or orientation of a given object in the scene. The shell prints the following error message: Error: signal 11: /home/marcofe1604/Documents/Software/V-REP_PR...

Hi, When I add a vision sensor object on a scene, it is oriented with the x-axis towards left and y-axis upward, but I would like to put in the conventional orientation used in literature (i.e., x-axis on the right and y-axis downward). So, I change the orientation of the sensor by rotation around t...

I solved my problem. The reason was not related to the CUDA support, but to the QT support. In particular, the version of QT with which OpenCV has been built was different from the version used to build V-REP. Downloading the proper QT version and re-building OpenCV with QT support did the trick. Th...

When I used my application outside V-REP I used the same flags and libraries, and the code worked. So I don't think it's a problem of compilation/linking flag missing. Perhaps it could be a problem of V-REP itself with a CUDA-enabled-version of OpenCV. Have you ever tested that?

I tried your suggestion, but it didn't give me new hints to find out the origin of the issue. By the way, after other trials, I observed that the problem is given by the CUDA modules of OpenCV: in fact, V-REP does not crash anymore and the plugin is loaded if OpenCV is built without enabling the CUD...

Thanks for your answer. Actually, I can't check anything because even a print in the first line of the v_repStart function is not shown when V-REP crashes. I have not so many code lines in my plugin: I simply defined a OpenCV black image cv::Mat at the beginning of the function v_repMessage, and I t...

Hi all, I wrote a c++ plugin, named DPD, that uses OpenCV libraries inside (highgui, imgproc, gpu, core ... ). However, V.REP cannot load it properly, it falls in segmentation fault when trying to load the plugin: Using the default Lua library. Loaded the video compression library. Add-on script 'vr...
